Epstopdf is a Perl script that converts an EPS file to an 'encapsulated' PDF file (a single page file whose media box is the same as the original EPS's bounding box). The resulting file suitable for inclusion by PDFTeX as an image. The script is adapted to run both on Windows and on Unix-alike systems. The script makes use of Ghostscript for the actual conversion to PDF. It assumes Ghostscript version 6.51 or later, and (by default) suppresses its automatic rotation of pages where most of the text is not horizontal. LaTeX users may make use of the epstopdf package, which will run the epstopdf script "on the fly", thus giving the illusion that PDFLaTeX is accepting EPS graphic files.
